Perhaps you should try some spelling variations:
"modified trained convolution algorithms" » "modified trained evolution algorithm", "modified trained solution algorithm", "modified trained convolutional algorithms", "modified traces convolution algorithms"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified trained convolution algorithms") OR ("modified one approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified trained convolution algorithms ) or ( modified one approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified trained convolution algorithms") or ("modified one approximation algorithms"))*.
